WHEEL-HARROW.

SPECIFICATION forming part of Letters Patent No. 610,300, dated September 6, 1898.

Application filed December 10, 1897. Serial No. 661,437. (No model.)

To all whom, it may concern.-

Be it known that I, NAPOLEON FOURNIER, a citizen of the Dominion of Canada, residing at St. Germain de Grantham, in the county of Drummond, Province of Quebec, Canada, have invented certain new and useful Improvements in Wheel Harrows; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in barrows, and has particular relation to that class of such devices known as wheel-harrows.

The object of my invention is to provide a device of this character in which the harrowteeth, while held in positive relation with the ground upon which they are operating, are arranged to allow of a change of such relation corresponding with the change in the topography of the ground, said change being made automatically, yet not disturbing any of the relations existing before the change, each tooth being adapted to perform the same functions, whether held in alinement or otherwise.

A further object is to provide a device which will be neat and attractive in appearance, durable in construction, and which is simple in its operation.

To these ends my invention consists in the improved construction and combination of parts hereinafter fully described, and particularly pointed out in the claims.

In the drawings, in which similar letters of reference indicate similar parts in all of the views, Figure l is a side elevation of a harrow, showing my improvements, one wheel being shown as removed. Fig. 2 is a top plan view of the same. Fig. 3 is an enlarged view in perspective, showing the arrangement of the barrow-teeth, two sections being shown, each section being on a different plane.

A designates an axle on which are mounted wheels a, preferably constructed of iron or steel in order that they maybe of light weight, yet capable of great strength. Suitable bearings a are mounted on said axle, to which is secured the frame B, formed of the side pieces I) Z), held in position by means of the surrounding band Z), which forms the front and rear portions of the frame.

Secured to the sides of the frame are vertically-depending hangers 12 12 in the lower ends of which are mounted rods 19 I), extending from one side of the frame to the other at the front and rear thereof. Braces 6 secured to the front and rear portions of the frame, extend downwardly and at their lower ends are mounted on said rods, serving to hold them in position regardless of the strain placed upon them when the device is being used. Pivotally mounted on said rods b b are bearings C, said bearings being of a length suflicient to occupy the entire space between the braces 6 and are provided at their centers with downwardly-extending portions 0, preferably of the form shown in Fig. 3. To the front face of each of these portions 0 are se cured the rearwardly-extendingharrow-teeth 0, preferably formed as shown in the drawings; but it is apparent that any suitable teeth may be used, the essential feature being that they must be springy. The bearings C are connected together in series, as best shown in Fig. 3, by braces 0 secured in the downwardly-extending portions 0, each series consisting of three teeth, the arrangement being such that alternate series have two teeth mounted on the rod b and one tooth mounted on rod b the remaining series being arranged vice versa, having one tooth on the rod 19 and two teeth on the rod 5 By this construction it is apparent that each series of teeth will move together when operated, while each series or section will be movable independently of the remaining sections.

Pivot-ally mounted in suitable bearings d, secured to the top of the side pieces I) b, is a roller D of suitable form, preferably octagonal, to the top side of which are secured suit able connecting means dsuch as chains, Wire rope, &c.--the free ends of which are adapted to be secured to the downwardly-extending portions 0, mounted. on the rod 17 An operating-handle d is mounted in said roller and is provided with a pawl 01 which engages with a segmental plate (1, mounted on the frame and extending a suitable distance around the roller D, the segmental plate being provided with notches d into which the pawl d is adapted to be placed and be held in engagement. The pawl d may be operated in any suitable manner, as by a bell-crank lever, the upper end of which is in a position near the upper end of the handle 61 or it may be operated by suitable foot mechanism of any approved form. It will be seen that when the pawl is freed from the notches the handle may be moved backward or forward, this movement causing a corresponding movement of the roller, which in turn raises and lowers the teeth 0 as the connection is wound or unwound on the roller D.

Each series of teeth or section is provided at its front end with an eye 0 to which is secured by suitable means one end of a singletree 0 the two singletrees being in turn connected by suitable connections with a doubletree 0 provided with the usual doubletree 0 and singletrees 0 to which the horses or other draft-animals are to be attached. This arrangement is such that when any one section is out of alinement, as when the harrow is being used on plowed ground and the furrows are deep and wide or when some obstruction is met by the teeth of the section, the movement of the section upward or downward will be communicated to the end of the singletree 0 connected to that particular section, the movement being in turn communicated to the end of the doubletree c to which the singletree is attached. It will be apparent, however, that the movement of the singletree 0 will be small by reason of its connection tothe section being close to the pivotal point of the bearings O, and by the use of the doubletree c this small movement will be greatly reduced and to such an extent that the change in position will have but a slight effect on the pulling of the draft-animals. It will also be seen that whether the movement of the section be upward or downward the change will be instantly communicated to the draft-animals, but in such manner that the pulling power of these animals will remain the same, and the work will be done in an even manner regardless of the fact as to whether the teeth are in alinement or not.

The depth to which the teeth will enter the ground is regulated by the position of the bearings C, and as the connection between the doubletree c and the bearings is a positive one it will be apparent that the doubletree must be movable backward and forward to correspond with the movement of the bearsection or series of teeth, the pulling power of the draft-animals remaining the same regardless of the changes of the teeth.

E designates a seat mounted to the frame in any suitable manner.

It is obvious from what is shown and above described thatI have provided a harrow which will be manufactured with a minimum number of parts and which is of a light weight, will yetbe absolutely certain in its operation, and is always under the control of the operator, who is able to regulate it at will.

Having thus described myinvention, what I claim as new is- 1. A harrow comprising a frame mounted on wheels; harrow-teeth pivotally connected to said frame, said teeth being arranged in sections, each section being movable independently of the remaining sections; and means, connected to said sections below the point of pivotal connection to said frame, for preserving an equalized pull on each of said sections, substantially as described.
